Is this a troll?

When you set that option, ffserver loads an encoder with name h264.
Since you have built ffmpeg without libx264, there is no h264 encoder.
So it is an unknown codec. If you build ffmpeg without libx264, you
cannot encode h264.

So your "h264" codec supports decoding of video, and can decode lossy
and lossless. It does not support encoding of video to H264. This is
because you have not built ffmpeg with libx264.

No libx264 => no H264 encoder => error when trying to find a H264 encoder.
